Hi, it looks like you created the subscription with a Microsoft account (gmail) and are viewing it from the wrong tenant: don't convert that account to "member", leave it as Guest; re-enter the portal by choosing "Sign in with Microsoft account" (not work/school), then use "Directory + subscription" to switch to the tenant containing the subscription; once inside, create a local cloud user (user@<tenant>.onmicrosoft.com), give it Global Administrator in Login ID and Owner or User Access Administrator on the subscription, also keeping your gmail as Guest + Owner; then in CLI do az login --tenant <tenantId> and az account set --subscription <subId> (your MissingSubscription error almost always arises from misaligned tenant/subscription); verify that Microsoft.Authorization is registered and that you have privileges to create assignments; To write secrets, assign "Key Vault Secrets Officer" (scope = vault ID) and use "Key Vault Administrator" only for vault management. Otherwise, if the vault is in "access policy" mode, set an access policy instead of RBAC. If you can no longer log in with Gmail, try logging in with a Microsoft account and changing directories. As a last resort, open a support ticket to restore the Owner status on the subscription.
